TAKE-UP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No, 388,615, dated August 28, 1888.

Application filed January 4, 1887. Serial No. 123,372. (No model.)

To all whom it may concern:

Be it known that 1, FREDERICK AUGUSTUS ARBENZ, a citizen of Switzerland, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Take Up Mechanism for Looms,which improvement is fully set forth in the following specification and accompany ing drawings, in which- Figure 1 represents a side elevation of a portion of a loom having the take-up mechanism embodying my invention applied thereto. Fig. 2 represents I a longitudinal vertical section in line as m, Fig. 3. Fig. 3 represents a transverse vertical section in line y Fig. 1.

Fig. 4 represents an end view of a modification. Fig. 5 represents a side elevation ofthe portion shown in Fig. 4. Fig. 6 represents a sideview of a modification. Fig. 7 represents a top view of another modification. Fig. 8

represents a side elevation of Fig. 7. Fig. 9.

represents a vertical section of the portion in line 2 2, Fig. 3.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to improvements in take-up mechanisms for looms; and it consists in the combination and arrangement of parts,

as hereinafter set forth and claimed, whereby the take-up operation is effectively accomplished, means being provided to prevent any undue strain owing to back action of the winding-drum.

Referring to the drawings, A represents the frame of a loom, and B the lay thereof, both of usual construction.

0 represents the reed located in a frame, the lower bar, 0, of which is secured to arms D, the upper ends whereof are fitted to journals D, which are mounted in bosses D rising from the lay. The upper cross-bar, D, of the said frame is connected with said armsD by means of bolts E, which are secured to the ends of said bar and pass through slots E in the arms D, whereby said cross-bar D may be vertically adjusted. The bolts E carry nuts E", which tighten against the arms D and serve to hold the bar D in adjusted position.

Attached to the ends of the bar 6 are arms F, whose lower ends carry pins F, each of which pins enters the bifurcated limb of a weighted elbow-lever,G,whose bearings are on the axes G of the lay. I

To one of the journals D is secured a vertical arm, H, to whose lower end is secured a rod, J ,which extends forward from said arm and is freely fitted to an arm, K,the latter having hung to it a pawl, K, which engages with a ratchet, L,on the shaft of a wheel of a train of gearing, M, one of said wheels being connected with the shaft of the winding-drum N of the loom.

P represents a check-pawl,which is mounted on the frame A and engages with the ratchet L for preventing return motion of the ratchet.

Q represents a spring which encircles the rod J and is interposed between the arm K and a collar, It, the latter being mounted on said rod J and having aside opening in which a screw is fitted, so that the said collar is adjustably connected with said rod J, whereby the tension of the spring may be adjusted. The arm K has an opening through which the rod J freely passes,the said rod having ascrewthreaded end for a nut, B, so as to secure the arm on the said rod.

It will be seen that the inner end of thejournal D, to which the arm H is secured, is squared, so as to enter an angular opening in the connected arm D, whereby as said arm D is moved it rotates said journal D, and consequently operates said arm H.

The operation is as follows: As the lay advances,the reed is stopped by contact with the fell of the cloth, and the lay still advancing, the journals D oscil'late in their bearings, the lower part of the arm F, carrying the pin F, being thrown backward, so as to press against the rear fork of the bifurcatedarm of the lever G, and thereby raise the weighted arm thereof, the said weighted arm causing the rear fork to press against the pin when the lay is pushed backward at the completion of the forward motion, and thereby restoring the reed toits normal or vertical position. At the time of the oscillation or partial rotary movement of thejournal D the arm H is movedso as to operate the arm J ,and thereby the arm K,in" such. manner that the pawl K on the upper part of said arm rides freely over the teeth of the rides freely over the ratchet.

ratchet L. When thelay returns,the weighted lever G causes the arms F to assume their normal positions, the return movement of the said arms F causing the journal D to so operate the arms H and J,and thereby the arms K,tl1at the pawl K is caused to rotate the ratchet L, and consequently the train of gearing M, whereby the drum N is rotated and the fabric wound thereon. Should there be any strain on the drum due to back action or resistance of the fabric. said strain being transmitted to the ratchet L, this occuring as the pawl advances, the lower end of the arm K slips on the rod J, whereby breakage of the pawl or the arm, or both, is prevented. \Vhen the strain is relieved, the spring Q restores the arm K to its normal position.

In Figs. 1, 3, and 4 I show in dotted lines a rod, J, and spring Q, one end of the rod be ing pivoted to the upper extended end of the arm K. The other end of the rod passes freely through the lay and carries a collar, R, between which and the lay the spring Q is located. In this case the spring ({g on the rod J is omitted, and the arm K is pivotally secured to the rod J; but the result is the same as that hereinbefore stated, the'operation being, however, slightly different, in that in the event of strain on the drum N as the pawl K advances the rod J causes the spring to yield, and thus relieve the pawl, and conse quently the arm K and connected parts.

In Figs. 4 and 5 the arm H is shortened and does not extend to thejournal D, but is extended laterally, joining one of the arms F, the locations of the elbow-lever G and pins F beingsomewhat raised from theposition shown in Figs. 1, 2, and 3, without, however, producing different results.

In Fig. 6 the arm H has its lower end forked to engage with a pin, F", on lever F, which is pivoted to the frame of the loom, said lever F having secured to its upper end an eye, Q, through which freely passes the rod J, the latter having the collars Q? and Q thereon. A spring, is interposed between the eye Q and the collar Q on the end of the rod J. As the lay advances and thejournal D is rocked by the movement of the arm D, the arm H is moved so that its lower forked end operates on the pin F of the lever F moving the lower end of said lever F to the right. This moves the upper end of the lever F to the left, and thus operates the rod J, whereby the pawl On the return motion the pawl rotates the ratchet, and in the event of strain on the latter the spring Q yields and prevents breakage of the parts.

In Figs. 7 and 8 one of the wheels M is a worm-wheel, and meshes with a worm, M, which is fixed to a shaft, M", on which is loosely fitted a collar, M, to which is hung one or more pawls, K, which engage with a ratchet, L, to which the shaft M is firmly secured. A rod, J, is connected with said collar M and operated similarly to the rod shown in Figs. 1, 2, and 6, and carries a spring for relief of the parts in the event of strain on the drum N.

The top of the arm H carries a weight, H, to assist in restoring said arm to its normal position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
